The Formula Explained
Critical Load Formula: P_{cr} = \frac{\pi^2 \cdot E \cdot I}{(KL)^2}
Glossary of Variables
| L | Length of the column |
| P_{cr} | Critical Load |
| K | Effective Length Factor |
| E | Modulus of Elasticity |
| I | Moment of Inertia |
How It Works: A Step-by-Step Example
For a steel column with a length of 5 meters under an axial load of 200 kN, using a modulus of elasticity of 210 GPa, calculate the critical load using the formula above. Steps include determining the effective length factor and moment of inertia based on column conditions.
